OVERVIEW AND KEY FEATURES
BT900 Series modules from Laird make it easy to add Classic BT and Bluetooth Low Energy (BLE) functionality to
small, portable, power-conscious devices, including those powered by batteries. The fully approved,
programmable modules feature Laird’s innovative, event-driven smartBASIC programming language, which
significantly reduces OEM development risk and speeds time to market.
Based on the Cambridge Silicon Radio (CSR) 8811 silicon and a low power Cortex M3 microcontroller, the BT900
modules provide exceptionally low power consumption with outstanding wireless range, all within a compact
footprint of 19 mm x 12.5 mm. The modules incorporate all the hardware and firmware required to support
development of Dual Mode applications, including:
▪ Complete radio hardware
▪ UART, I2C, SPI, ADC, and GPIO interfaces
▪ Embedded BTv4.0 software stack
– Classic BT profile - SPP
– GATT Client and Peripheral modes
What makes the modules truly innovative is smartBASIC, an event-driven programming language that enables
standalone operation of the module. Laird has extended the implementation of smartBASIC from the popular
BL6xx series of single mode BLE modules into the BT900 series. This allows developers the flexibility of utilising
the Core and BLE specific smartBASIC functions from the BL6xx series to create fully interchangeable BLE
applications between these product ranges.
Without the need for any external processor, a simple smartBASIC application encapsulates the complete end-to-
end process of reading, writing, and processing of sensor data and then using Classic Bluetooth or BLE to transfer
it to / from any Bluetooth device. Ultimately smartBASIC accelerates initial development, creation of prototypes,
and mass production by providing you with your own Bluetooth expert within the module.
In addition to carrying FCC modular, IC, CE and MIC approvals, BT900 modules are fully qualified as a Bluetooth
product, enabling designers to integrate the modules in devices without the need for further Bluetooth testing. A
low-cost developer’s kit including simple software tools simplifies module integration and guarantees the fastest
route to market.
